Subject: [PATCH v2 1/1] Fix documentation for wal_summary_keep_time.

The documentation for this parameter lists its type as Boolean, but
it is actually an integer.  Furthermore, there is no mention of how
the value is interpreted when specified without units.  This commit
fixes these oversights in commit 174c480508.

        This parameter can only be set in the
        <filename>postgresql.conf</filename> file or on the server command line.

        The default is 10 days. If <literal>summarize_wal = off</literal>,
        existing WAL summaries will not be removed regardless of the value of
        this parameter, because the WAL summarizer will not run.
